Lets's calculate LCM of 23,25,18,97

Given numbers has no common factors except 1. So, there LCM is their product i.e 1003950

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1003950

Therefore, the GCF of Fractions 42/23,64/25,55/18,88/97 is 1/1003950

Least Common Multiple of 23,25,18,97 with GCF Formula

Least Common Multiple of 23,25,18,97 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 23,25,18,97 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(23,25,18,97) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(23,25,18,97) x common factors =1 x 1 = 1

LCM(23,25,18,97) = ( 23 × 25 × 18 × 97 ) / 1

LCM(23,25,18,97) = 1003950 / 1

LCM(23,25,18,97) = 1003950
